Study Finds Effective Methods for Smoking Cessation
A study found that varenicline, bupropion, and low-dose e-cigarettes were the most effective smoking cessation methods.

A study titled "Pharmacological and e-cigarette intervention for smoking cessation: systematic review, network meta-analysis, and cost-effectiveness analysis" was conducted by researchers at the University of Bristol in the UK. They searched a publication database up to March 2017 and updated their search in February 2019 with randomized clinical trials of smoking cessation interventions lasting for over six months.


The research team ultimately conducted a total of 363 experiments involving 201,045 participants. Additionally, they conducted 53 observational studies, which involved 8,783,5403 participants for safety review purposes.


After analyzing the results, the research team has concluded that the most effective treatment methods are substituting with Varencicline Standard plus Nicotine (odds ratio [OR], 3.22; 95% credible interval [CrI], 2.27-14.88), substituting with Varenicline Low plus Nicotine (OR, 5.70; 95% CrI, 1.57-21.12), and using low electronic cigarettes (OR, 3.22; 95% CrI, 0.97-12.55).


A controversial drug.


On October 1, 2021, the drug varenicline, commonly sold under the name Champix, was added to the World Health Organization's Essential Medicines List. This anti-smoking medication is well-known for helping smokers overcome cravings for cigarettes. However, despite being considered highly effective, it can also cause moderate to severe psychological side effects, ranging from terrifying nightmares to suicidal thoughts.


After multiple reports of such disturbances, the US Food and Drug Administration (FDA) issued the most severe warning for the drug, causing the sales of Valeni-cline to decrease from $846 million in 2008 to $671 million last year.


In order to overcome this decline, Pfizer, the manufacturer of the drug, has invested heavily in advertising and resolving lawsuits related to the medication. Additionally, the pharmaceutical company has released data retrieved from a study that allegedly proves that consuming Valenicline does not have a direct link to experiencing psychological disorders.


Subsequently, after refusing to lift the warning in 2014, the FDA recently decided to change their stance and abandon the warning. The agency has requested the listing of side effects associated with the drug, and has established a requirement that the label specify that varenicline is more effective than other smoking cessation therapies.


Vonnicron stock recall


Meanwhile, in June of last year, Pfizer was forced to halt distribution of Valsartan after discovering increased levels of nitrosamine in the pills and recalled some of its stock. However, in the following month, the US Food and Drug Administration announced that it would temporarily allow some manufacturers to distribute drugs containing carcinogens below a temporary limit of 185 nanograms per day until impurities could be eliminated or reduced to acceptable levels.

FDA Appoints Former Tobacco Enforcement Deputy Jessica Zeller as Director as Agency Weighs PMTA Framework Changes
The U.S. Food and Drug Administration (FDA) has named Jessica Zeller director of the Center for Tobacco Products' (CTP) Office of Compliance and Enforcement (OCE), effective November 1, 2026. Zeller, the office's inaugural deputy director, returns from medical device manufacturer Edwards Lifesciences with more than 20 years of regulatory and legal experience. The appointment follows CTP leadership changes and adjustments to tobacco regulation. Bret Koplow became permanent CTP director in September; the FDA revised enforcement priorities for unauthorized e-cigarettes and nicotine pouches in May and announced faster PMTA review procedures. On September 28, the agency said it would evaluate changes to the existing PMTA regulatory framework, including potential rulemaking to replace it.

GAO Audit Finds Nearly 132,000 FDA Tobacco Applications Waiting an Average 1,266 Days as Nicotine Pouch Pilot Practices Move Into Vape PMTA Reviews
GAO Audit Finds Nearly 132,000 FDA Tobacco Applications Waiting an Average 1,266 Days as Nicotine Pouch Pilot Practices Move Into Vape PMTA Reviews
A U.S. Government Accountability Office audit found that 131,915 tobacco product applications submitted to the FDA since 2018 remained without a final review as of December 31, 2025, with pending applications waiting an average of 1,266 days. GAO also found FDA lacks the data needed to systematically determine whether scientific reviews meet applicable timelines. HHS agreed to upgrade the agency's tracking systems. At the same time, FDA has begun applying lessons from its nicotine pouch PMTA pilot to e-cigarette reviews, while changes to enforcement policy and electronic submissions are making the specific stage of a PMTA increasingly relevant to market access.

Special report|Indonesia's Vape Industry Has 200 Manufacturers and $1.7 Billion in Investment. Could a Regulatory Divide Derail Its Rise as the World's No. 2 Manufacturing Hub After Shenzhen?
Indonesia's Ministry of Industry said at a November 3, 2026, policy forum that the country has about 200 electronic cigarette companies, Rp31 trillion (approximately $1.71 billion) in cumulative industry investment and around 100,000 jobs across the supply chain. The National Narcotics Agency is seeking a comprehensive ban on vape use and circulation, while the industry ministry favors tighter import, product-standard and distribution controls. Indonesia exported approximately $518 million in vaping products in 2025, and Chinese manufacturers including Smoore, GEEKVAPE and Jinjia Group have established local operations. An international logistics specialist interviewed by 2Firsts said more Chinese vape companies began production in Indonesia from the second half of 2025, accompanied by increased shipments of manufacturing equipment and investment in logistics facilities. The regulatory debate comes as Indonesia expands its role in international vaping manufacturing.

Special Report | Vape bans and tougher rules: the South Caucasus takes different paths
Azerbaijan's sweeping e-cigarette ban has raised concerns over enforcement errors and the emergence of illicit sales, while neighboring Armenia is tightening technical rules and preparing higher excise taxes. Georgia, meanwhile, has resisted calls for broader vape restrictions and introduced preferential taxes for some domestically produced cigarettes. The divergent approaches across the South Caucasus highlight a regional policy dilemma: how to curb nicotine use and protect public health without encouraging black markets or creating unintended economic consequences for businesses and consumers.
